Product Description:
The AL2406-0001-0000 is a coil unit in the Beckhoff AL Linear Motors series and is part of the company’s linear servo motor range. As a moving primary component, it interacts with a passive magnet track to generate direct linear thrust without requiring a mechanical transmission. This arrangement supports precise positioning in pick-and-place axes, gantries, and other machinery that benefits from responsive linear movement.
The coil block delivers a continuous force of 120 N when cooled by ambient air while drawing a steady current of 3.08 A. During rapid acceleration, it can accept up to 8.20 A, allowing a peak thrust of 240 N for short intervals. Its internal back EMF constant is 22.63 V/m/s, indicating the voltage induced for each unit of travel speed and supporting drive selection and servo-loop tuning. Magnetic attraction toward the stator rail reaches 500 N, so the mounting fixtures must withstand the resulting preload. The six-coil assembly uses a 24 mm pole pitch that aligns with the magnet spacing, and an air gap of 0.5 mm must be maintained for consistent force production. Its speed-oriented winding has a phase-to-phase inductance of 34 mH and a resistance of 5.4 Ω, keeping the electrical time constant suitable for fast current control. The unit weighs 0.9 kg and is supplied without connectors or water cooling, simplifying its cable arrangement and eliminating the need for coolant lines.
A motor constant of 190 N²/W relates usable thrust to winding heat dissipation. The coil has a thermal resistance of 0.75 °C/W and a thermal time constant of 75 s, indicating how its temperature responds during operation. Continuous power loss is 99 W, so an appropriate heat sink or forced airflow may be needed during demanding duty cycles. A power constant of 39 N/A supports estimates of dynamic force from the applied current. The overall width is 50 mm, allowing the compact coil block to fit closely spaced linear stages. Its narrow form and six-coil arrangement also support multi-track machine layouts where available installation space is limited.
